All 176 people on board a passenger plane were killed when the aircraft crashed a few minutes after taking off from Iran's Imam Khomeini on Wednesday, January 8, due to technical snags. The plane was bound for the Ukrainian capital Kyiv. The Boeing 737 belonging to Ukraine International Airlines took off at 6.12 am local time and crashed about eight minutes later.

"The fire is so heavy that we cannot (do) any rescue... we have 22 ambulances, four bus ambulances and a helicopter at the site," Pirhossein Koulivand, head of Iran's emergency services, told state television. According to air tracking service FlightRadar24, the aircraft that crashed was Flight PS 752 and was flying to Kyiv. The plane was three years old and was a Boeing 737-NG, it said.
